SPECIFICATION forming part of Letters Patent No. 269,409, dated December19, 1882.

Application filed August 16,1882. (No model.)

To all whom it may concern:

Be it known that I, FRANK H. GOWELL, of Boston, in the county of Suffolkand State of Massachusetts, have invented a new and Improved Oil-StoneBlock, of which the followingis a full, clear, and exact description.

The object of my invention is to provide anew and improved device forholding an oilstone in such a manner that it can be adjusted so thateither of its four longitudinal surfaces will be on top.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding pgmts in all the figures.

Figure l is a longitudinal sectional-elevation of my improved oil-stoneblock. Fig. 2 Fig. 3 is an end elevation of the pivot-block for holdingone end of the stone.

Two legs, A A, are united by a screw-rod, B, to form a frame in whichthe oil-stone O is held. A block or plate, D, provided on one side withstuds E and on the opposite with a recess or aperture, F, is held on oneend of the stone 0, the pegs or studs E passing into recesses in the endof the stone, and a pivot, Gr,

projecting from the inner surface of the leg A, passing into the recessF. A block, H, provided on one side with studs or pegs J, adapted to bepassed into recesses in the opposite end of the stone, is provided witha threaded aperture adapted to receive the end of a screw, K, passing.loosely through an aperture in the leg A. The stone 0 is thus adapted toturn on the pivot G and the screw K, and can be turned or adjusted sothat either of its four longitudinal surfaces will be on top. Afteradjustment the stone can be locked in K to such an extent that the leg Ais clamped H, by which means the stone is held so firmly that it cannotturn. 1

By means of the above-described oil-stone block or holder all fourlongitudinal surfaces of the oil-stone can be utilized for sharpeningtools.

Havin g thus described my invention, I claim as "new and desire tosecure by Letters Paten t- 1. The blocks D H, which hold an oil-stonebetween them,combined with the supportingframe. by a pivot and screw,whereby either of the longitudinal surfaces of the oil-stone may bebrought on top, as desired.

2. In an oil-stone holder, the combination, with the legs A A, of thescrew-rod B, the pivot-block D, the block H, and the screw K,substantially as herein shown and described, and for the purpose setforth.

3. In an oil-stone holder, the combination, with the legs A A, of thescrew-rod B, the pivot G, the block D, provided with studs E, the blockH, provided with studs J, and the screw K, substantially as herein shownand described, and for the purpose set forth. FRANK H. GOWELL.Witnesses:
